Had the receiver for almost a year now. Immediately I noticed that the receiver itself (not through speakers) makes a clicking sounds when the output settings change (for example 7.1 dropped own to 5.1, happens quite a bit when playing media on the PS3). Wasn't bothered by it... until I had cable television installed today. Every other channel outputs something different, so I'm getting clicks all over the place. Is there a way to get rid of the clicking when the sources changed? Or is this common thing?
